Livestock dusting bag

ABSTRACT

A self-dusting cartridge loading protected livestock applicator comprising an inner porous bag having filling means and flexible protective material substantially surrounding and secured to the bag. The flexible protective material extends below the inner porous bag forming folds which curl upward toward the bottom of the inner porous bag and preferably extend upward with a porous material that contacts and transfers dust from the inner bag to itself and to an animal. The applicator is constructed so that when it is agitated by an animal the guard or protective flaps cause dust to be dispensed on the agitating animal and at the same time provide some protection to the more vulnerable inner bag.

i z /wme qm ATTORNEYS LIVESTOCK DUSTING BAG This invention applies to an applicator for dusting livestock with insecticide powders or dust as the animal passes beneath the applicator.

It is well known that livestock are frequently troubled with various types of insects such as flies, ticks, lice, etc. which prey upon them causing irritation which results in interference of the animalsgrazing and feeding. This interference can result in a loss of weight, decrease of milk production or impairment of the hide.

In the past there have been several conventional ways that this pest problem has been dealt with. One conventional way was to individually treat each animal by hand, which is an expensive method of treatment due to the individual cost of the labor involved. Additional treatments that have also been used are in the form of dust bags which are supported by various means. These dust bags are usually simple burlap type bags, or other more sophisticated bags that'use poly type materials around the bag to protect them from moisture. The useful life of such bags has been limited due to the fact that the bag material has a tendency to easily become clogged with the dirt, saliva, feed and natural oils that accumulate on the bag when animals come into contact with them.

The present invention is an improvement over previous dust applicators and is constructed with an outer layer of heavy flexible material substantially encompassing and secured to an inner porous bag so that the edges of the outer heavy flexible material extend down and under the inner porous bag forming folds. The fold arrangement acts as a protective guard flap in two ways. I

1. It protects the more vulnerable'inner dust carrying bag from the abuse of the cattle agitating the bag and also absorbs or collects much of the foreign matter from the cattle preventing the foreigdmatter from plugging the porous inner dust carrying bag.

.2. It offersprotection of the inner dust carrying bag from the elements and due to the heavy outer cover, the inner dust carrying bag is in a sense hanging in deep shade and the sun's ultra violet penetration is greatly reduced. This configuration also offers some protection from wind and moisture.

The unique, cartridge loading livestock dusting bag or applicator 10 in FIGS. 1, 2 and 3 includes an .inner Preferably, the heavy flexible material-forms an outer bag lined in the inside with porous material for receiving and also applying dust to the using animal. This outer bag has the feature of exposing a greater dusting area when agitated since it is split part way up both its outer ends and depending on the direction or angle of the blow struck offers protection to the inner dust carrying bag.

The normal use of the present invention lends itself to a longer serviceable-life than a conventional applicator or bag which comes into contact-with moisture, dirt and other clogging materials as well as the ultra violet rays of the sun, causing it to rot. Consequently, the present inventions improved construction and material composition enable it to be used longer than conventional dust bags. In fact, the present invention can be reused, as a refiller valve or spout is incorporated in the construction of the inner dust bag of the applicator which allows the user to conveniently-refill the bag, thus lowering the cost per pound of dust dispensed.

These and other objects and advantages of theinvention will appear more clearly from the following specifiporous dust storing and dustingbag 1 2, andas shown is filled with insecticide dust or powder l4. Preferably, bag 12 consists of two layers of burlap or, e.g., one inner layer 13 of burlap and an outer layer 15 of polyester woven material. Bag '12 is closed at both ends and its sides 16 extend upwardly toward each other to a closen top-end 18. With this arrangement, several important advantages are obtained. First, the inner layer 13 of burlap carries little orno weight of the dust 14 since it is supported by the outer layer 15. Second, the burlap layer 13 or layer 15 does not come. into contact with the saliva, feed, water, dirt, hair and oils or other foreign material from the cattle which ordinarily would result in clogging of the burlap layeras the Outer guard flaps protect them.

' The inner bag 12 is fully protected from weather by two. guard flaps20 and 22 on oppositesides of bag 12. As indicated in FIG. 3, these flaps not only fully cover both sides of bag 12 but also extend substantially beyond the opposite ends of the bag to effect a substantial cover of bag 12 all the way around. Flaps 20 and 22 include an outer wall 24 which is of flexiblematerial, .for example cloth, burlap if desired, covered with a suitableheavy flexible material. Each outside wall provides skirt means which extends considerably below the bottom of bag 12, for example a distance about equal to one-half the maximumwidth of bag 12 whenfilled, and at its lower end curls inward and upward tomake a U- shaped drip cap 26 for keeping moisture and foreign matter away from the inner bag 12. That is, any moisture on outer wall 24 runs down the wall and drips off at its lower end 26, thereby preventing moisture from coming into contact with bag 12 duringuse of the dust applicator 10 by wet livestock as shown in FIG. 1.

Flaps 20 and 22 preferably include an inner wall 28 forming each flap into an outer bag the ends of which are sewn shut or otherwise secured together and the interior of which also contains insecticides dust 30, which may be transferred thereinto from bag 12 in either or both of two ways. For example, direct, open transfer channel means such as grommets 32 and 34 may be disposed through apertures in opposite side walls 16 of inner bag 12 and respective inner walls 28 of the outer bags 20 and 22, approximately half way between the bottom of bag 12 and the normal fill level 35 of dust 14 therein. Of course, there may be more grommets per side than the two grommets 32 shown in FIG. 3. In addition to such grommet transfer means, or instead thereof, inner walls 28 may each be made of porous material, such as burlap cloth, whereby transfer of dust from the inner storage bag 12 to the guard flaps or outer bags 20 and 22 takes place automatically upon contact between bag 12 and inner walls 28 during use of applicator 10.

As more particularly shown in FIG. 2, outer wall 24 also extends upwardly along side walls 16 of bag 12, and forms a protective top cover, with the inner and outer bag walls being secured together in any desired manner, as by several straps that also provide the means for the complete assembly to be hung with an rope from a over head structure. These straps are staggered in their attachment to opposite sides of the bag so that each single strap offers two bearing points. In the case of four straps, eight bearing points are effected and dispersement of weight is reduced per bearing point and the weight of the hanging bag is evenly spread the length of the protective top.

As above indicated, burlap cloth is a preferable porous material for inner layer 13 on inner bag 12 and inside flap walls 28, but of course any other porous material may be used as long as it will sufficiently convey the powder or dust to the animal. Any desirable heavy flexible material can be employed on the outer walls 24 (guard flap 26).

In operation, the dust applicator is hung so that the lower, guard flap ends 26 are six to eight inches below the back line of the animal 42 to be dusted. As the animal passes under the applicator, contact is first made with the flexible outer side 24 of the leading flap 22, pushing the inner side 28 thereof against the inner bag 12 which contains the insecticide dust. This transfers dust into bag 22 via grommet 34 if such exists and- /or via the pores in bag 12 and side wall 28 (if the latter is porous as is preferred). As the animal passes on under the applicator, contact is made with the inner wall 28 of the other guard flap or outer bag 20, and assuming that it has already been charged with dust, and since it hangs below the bottom of the inner bag 12, it drags across the head and back line of the animal, dusting as it passes. During this process, dust is also emitted from the inner bag 12 directly onto the animal. In use, the combination of the exposed dusting area of the inner bag and the guard flap dusting walls 28 have a greater exposed dusting surface and consequently a greater efficiency and a better dusting potential, than a conventional bag, since the side flaps or bags of the present invention are constantly being charged and emitting dust along with the main bag 12. Dusting of an animal is also accomplished when it stands beside the bag and bucks and tosses it with its head. It will be realized that the arrangement of the dust bag of the present invention protects the bag 12 from much of the stress and wear resulting from animal contact since, as most blows from the animals horns or head are usually directed upwardly, the guard flaps 20 and 22 will conform to the bottom side of the dust bag 12 and absorb the blows from the animals. Moreover, as shown in FIG. 1, when an animal passes under the dust bag, the leading guard flap first comes into contact with the animal and folds under the dust bag 12 to absorb most of the oil, dirt and other clogging materials and functions to keep the dust bag 12 out of contact with the animals.

In an embodiment wherein grommets 32 and 34 are employed, two or more such transfer grommets being preferably used on each side of the bag, the outer dust flaps 20 and 22 are immediately charged by the dust 14 inside bag 12 upon hanging of the applicator in place. As the top level of the dust drops below the grommet level, the lifting action caused by livestock using the applicator raises the bottom level of the dust allowing the transfer grommets 32 and 34 to function until almost if not all of the dust is used.

If desired, the weatherproof dust bag of this invention may be used as a throwaway item. That is, once its contents have been used, a new bag may be hung in its place.

Alternatively, since the protection provided by this invention gives the applicator 10 a much longer serviceable life than a conventional bag that rots from moisture and the ultraviolet rays of the sun, refill provisions are desirable. As shown in FIGS. 4-9, inner bag 12' has a flexible filler valve or spout 42 through which insecticides may be inserted. This bag can be filled at the dusting location, with an insecticide dust cartridge 44 being inserted into the bag through spout 40. The dust applicator may be shipped with or without one or more insecticide cartridges. FIG. 4 shows the insertion of one such cartridge into bag 12 and when the operator needs to use the dust applicator, he reaches through the spout 42 and punctures or slits the cartridge or cartridges as shown by FIG. 5. Dust or insecticide then spills out into the applicator and the action of the animal bumping the bag will cause the contents thereof to be dispensed during the self-dusting operation by the animal. I

When more than one cartridge 44 is used, as shown in FIG. 5 the middle bottom portion of bag 12 is preferably sewn in a manner to cause a V void 46 to remove weight from center of bag. This eliminates sagging of the dust bag in the center causing the bottom to be level.

FIGS. 6 and 7 show the details of the filler valve or spout 42 with its support stitching 48, eyelet 50 and valve tie cord 52. When the bag is filled with an insecticide cartridge the inner bag 12' is closed as shown in FIG. 8 by tieing the valve tie cord 52 around the ends of the filler valve or spout 42 and then the valve is pushed inside the bag with the pull cord 52 hanging outside thereof if desired, as shown in FIG. 9. Any other type of closure means may of course be utilized to close the end of the tiller valve or spout 40.

Thus, it has been shown that all of the objects and advantages of this invention heretofore discussed have been carried forth by the construction and operation of the novel cartridge loading livestock dusting applicator above described. Further objects and advantages, and even other embodiments of this application, will become apparent to those of ordinary skill in the art upon reading the foregoing disclosure. However, it is to be understood that such modifications and variations are considered to'be within the purview and scope of the present invention as defined by the appended claims.
